ABSTRACT

The present invention relates to aminocyclohexanol derivatives useful for the treatment and/or prophylaxis of diseases which are associated with 2,3-oxidosqualene-lanosterol cyclase such as hypercholesterolemia, hyperlipemia, arteriosclerosis, vascular diseases, mycoses, gallstones, tumors and/or hyperproliferative disorders, and treatment and/or prophylaxis of impaired glucose tolerance and diabetes.

FIELD OF THE INVENTION

[0001] The present invention is concerned with novel aminocyclohexanol derivatives, their manufacture and their use as 2,3-oxidosqualene-lanosterol cyclase inhibiting medicaments.

BACKGROUND OF THE INVENTION

[0002] Causal risk factors that directly promote the development of coronary and peripheral atherosclerosis include elevated low-density lipoprotein cholesterol (LDL-C), low high-density lipoprotein cholesterol (HDL-C), hypertension, cigarette smoking and diabetes mellitus. Other synergistic risk factors include elevated concentrations of triglyceride (TG)-rich lipoproteins, small, dense low-density lipoprotein particles, lipoprotein (a) (Lp(a)), and homocysteine. Predisposing risk factors modify the causal or conditional risk factors and thus affect atherogenesis indirectly. The predisposing risk factors are obesity, physical inactivity, family history of premature CVD, and male sex. The strong connection between coronary heart disease (CHD) and high LDL-C levels in plasma, and the therapeutic advantage of lowering elevated LDL-C levels are now well established (Gotto et al., Circulation 81, 1990, 1721-1733; Stein et al., Nutr. Metab. Cardiovasc. Dis. 2, 1992, 113-156; Illingworth, Med. Clin. North. Am. 84, 2000, 23-42). Cholesterol-rich, sometimes unstable, atherosclerotic plaques lead to the occlusion of blood vessels resulting in an ischemia or an infarct. Studies with respect to primary prophylaxis have shown that a lowering of plasma LDL-C levels in plasma reduces the frequency of non-fatal incidences of CHD, while the overall morbidity remains unchanged. The lowering of plasma LDL-C levels in patients with pre-established CHD (secondary intervention) reduces CHD mortality and morbidity; meta-analysis of different studies shows that this decrease is proportional to the reduction of the LDL-C (Ross et al., Arch. Intern. Med. 159, 1999, 1793-1802).

[0003] The clinical advantage of cholesterol lowering is greater for patients with pre-established CHD than for asymptomatic persons with hypercholesterolemia. According to current guidelines, cholesterol lowering treatment is recommended for patients who had survived a myocardial infarct or patients suffering from angina pectoris or another atherosclerotic disease, with a target LDL-C level of 100 mg/dl.

[0004] Preparations such as bile acid sequestrants, fibrates, nicotinic acid, probucol as well as statins, i.e. HMG-Co-A reductase inhibitors such as simvastatin and atorvastatin, are used for usual standard therapies. The best statins reduce plasma LDL-C effectively by at least 40%, and also plasma triglycerides, a synergistic risk factor, but less effectively. In contrast, fibrates reduce plasma triglycerides effectively, but not LDL-C. Combination of a statin and a fibrate proved to be very efficacious in lowering LDL-C and triglycerides (Ellen and McPherson, J. Cardiol. 81, 1998, 60B-65B), but safety of such a combination remains an issue (Shepherd, Eur. Heart J. 16, 1995, 5-13). A single drug with a mixed profile combining effective lowering of both LDL-C and triglycerides would provide additional clinical benefit to asymptomatic and symptomatic patients.

[0005] In humans, statins are well tolerated at standard dosage, but reductions in non-sterol intermediates in the cholesterol synthesis pathway, such as isoprenoids and coenzyme Q, may be associated with adverse clinical events at high doses (Davignon et al., Can. J. Cardiol. 8, 1992, 843-864; Pederson and Tobert, Drug Safety 14,1996, 11-24).

[0006] This has stimulated the search for, and development of compounds that inhibit cholesterol biosynthesis, yet act distal to the synthesis of these important, non-sterol intermediates. 2,3-oxidosqualene:lanosterol cyclase (OSC), a microsomal enzyme, represents a unique target for a cholesterol-lowering drug (Morand et al., J. Lipid Res., 38, 1997, 373-390; Mark et al., J. Lipid Res. 37,1996, 148-158). OSC is downstream of farnesyl-pyrophosphate, beyond the synthesis of isoprenoids and coenzyme Q. In hamsters, pharmacologically active doses of an OSC inhibitor showed no adverse side-effects, in contrast to a statin which reduced food-intake and body weight, and increased plasma bilirubin, liver weight and liver triglyceride content (Morand et al., J. Lipid Res., 38, 1997, 373-390). The compounds described in European Patent Application No. 636 367, which inhibit OSC and which lower the total cholesterol in plasma, belong to these substances.

[0007] OSC inhibition does not trigger the overexpression of HMGR because of an indirect, negative feed-back regulatory mechanism involving the production of 24(S),25-epoxycholesterol (Peffley et al., Biochem. Pharmacol. 56, 1998, 439-449; Nelson et al., J. Biol. Chem. 256, 1981, 1067-1068; Spencer et al., J. Biol. Chem. 260, 1985, 13391-13394; Panini et al., J. Lipid Res. 27, 1986, 1190-1204; Ness et al., Arch. Biochem. Biophys. 308, 1994, 420-425). This negative feed-back regulatory mechanism is fundamental to the concept of OSC inhibition because (i) it potentiates synergistically the primary inhibitory effect with an indirect down-regulation of HMGR, and (ii) it prevents the massive accumulation of the precursor monooxidosqualene in the liver. In addition, 24(S),25-epoxycholesterol was found to be one of the most potent agonists of the nuclear receptor LXR (Janowski et al., Proc. Natl. Acad. Sci. USA, 96, 1999, 266-271). Considering that 24(S),25-epoxycholesterol is a by-product of inhibition of OSC it is hypothesized that the OSC inhibitors could also indirectly activate LXR-dependent pathways such as (i) cholesterol-7-alpha-hydroxylase to increase the consumption of cholesterol via the bile acid route, (ii) expression of ABC proteins with the potential to stimulate reverse cholesterol transport and increase plasma HDL-C levels (Venkateswaran et al., J. Biol. Chem. 275, 2000, 14700-14707; Costet et al., J. Biol. Chem. June 2000, in press; Ordovas, Nutr Rev 58, 2000, 76-79, Schmitz and Kaminsky, Front Biosci 6, 2001, D505-D514), and/or inhibit intestinal cholesterol absorption (Mangelsdorf, XIIth International Symposium on Atherosclerosis, Stockholm, June 2000). In addition, possible cross talks between fatty acid and cholesterol metabolism mediated by liver LXR have been hypothesized (Tobin et al., Mol. Endocrinol. 14, 2000, 741-752).

[0712] The compounds of formula (I) can be manufactured by the methods given below, by the methods given in the examples or by analogous methods. Appropriate reaction conditions for the individual reaction steps are known to the person skilled in the art. Starting materials are either commercially available or can be prepared by methods analogous to the methods given in the examples or by methods known in the art.

[0713] Scheme 1a:

[0714] The preparation of the starting materials for aminocyclohexyl derivatives of formula (I) in which V is O or S is depicted in scheme 1a.

[0715] For compounds with n=0, the synthesis starts from trans-4-aminocyclohexanol 1 which is converted to the Z-derivative or the BOC derivative 2 e.g. ZCl, Na₂CO₃, THF, H₂O or (BOC)₂O, iPrOH, CH₂Cl₂, respectively (step a). Lithium aluminum hydride reduction yields trans-4-methylaminocyclohexanol which is either BOC-protected to yield compound 3 or is directly transferred into the desired A⁶W-derivative 4 using one of the methods described later for compound 3 or 5 in scheme 3. If needed, the aminocyclohexanol derivative can be treated with hexamethyldisilazane at reflux, prior to the introduction of the A⁶W-moiety. Alternatively, the residue A⁵ can be introduced via alkylation using sodium hydride and a reactive alkyl or arylalkyl derivative (step b). BOC-deprotection (TFA, CH₂Cl₂) or Z-deprotection (hydrogenation) followed by treatment with A⁶W-derivatives gives compounds of the formula 4.

[0716] For n=1, the starting material is (trans)-4-tert-butoxycarbonyl amino-cyclohexane-carboxylic acid 5. This is converted to the derivative 6 by ester formation (e.g. carbonyl-di-imidazole, methanol in THF) and direct alkylation using sodium hydride and a reactive alkyl or arylalky derivative (step d). Reduction with lithium aluminum hydride yields the protected alcohol 7.

[0717] For n=2, the starting material is trans-4-aminocyclohexyl acetic acid (can be derived from 4-nitrophenylacetic acid according to Karpavichyus, K. I.; Palaima, A. I.; Knunyants, I. L.; BACCAT; Bull.Acad.Sci.USSR Div.Chem.Sci. (Engl.Transl.); EN; 29; 1980; 1689-1694; IASKA6; Izv.Akad.Nauk SSSR Ser.Khim.; RU; 10; 1980; 2374-2379 or T. P. Johnston et al. Journal of Medicinal Chemistry, 1977, Vol, No.2, 279-290.) which can be converted to the corresponding alcohol following the protocol for the compounds 5 to 7.

[0718] For n>=3, the starting material is (trans)-4-tert-butoxycarbonyl amino-cyclohexane-carboxylic acid 5. Chain elongation can be achieved using methods known in the art or as described below:

[0719] For C₂-elongation: Swern oxidation of the alcohol 7 to the corresponding aldehyde followed by Horner-Emmons reaction with triethyl phosphono acetate, sodium methanolate in ethanol gave the unsaturated ester 8. This was subjected to hydrogenation with 10% palladium on carbon in methanol and reduction with lithium aluminum hydride in THF to yield the chain-elongated alcohol 4. This sequence can be repeated to get the C₄-elongated alcohol 4.

[0720] For C₂ up to C_((n-1))-elongation Corey-Fuchs methodology may be used: Therefore, acid 5 is converted to the Weinreb derivative by treatment with N,O-dimethyl-hydroxyl-amine.hydrochloride with EDCI and HOBT in CH₂Cl₂ at room temperature which is reduced by lithium aluminum hydride to the corresponding aldehyde 9 (step i). This aldehyde 9 can be treated with triphenylphosphine, tetrabromomethane and triethylamine in CH₂Cl₂ at 0° C. to RT to yield 2,2-Dibromo-vinyl derivative 10. Rearrangement with n-BuLi (ca 1.6 M in hexane) in THF at −78° C., followed by reaction with formaldehyde (−78° C. to RT) gives the propargyl alcohol [step 1, following conditions described in: Marshall, James A.; Bartley, Gary S.; Wallace, Eli M. Total Synthesis of the Pseudopterane (−)-Kallolide B, the Enantiomer of Natural (+)-Kallolide B. J. Org. Chem. (1996), 61(17), 5729-5735; and Baker, Raymond; Boyes, Alastair L.; Swain, Christopher J. Synthesis of talaromycins A, B, C, and E. J. Chem. Soc., Perkin Trans. 1 (1990), (5), 1415-21.], from which the propanol derivative 4 can be obtained by hydrogenation with 10%Pd/C.

[0721] For longer side chains, the rearrangement is performed with n-BuLi (ca 1.6 M in hexane) in THF at −78° C. as above, followed by addition of a cosolvens such as DMPU and reaction with O-protected 1-bromo-alcohols 11 (step m; e.g. 1-bromo-n-tetrahydropyaranyloxyalkane) to give the O-protected compounds 12.12 can be converted to the alkanol derivatives by hydrogenation with 10%Pd/C followed by deprotection to yield the derivatives 4.

[0722] If WA⁶ is a protective group, this maybe cleaved as described for derivative 3 and the final moieties WA⁶ may be introduced as described for the compounds in scheme 3.

[0723] Scheme 1b:

[0724] Scheme 1b describes the synthesis of pure trans-aldehyde building block 8. A⁵ substituted 4-aminocyclohexanol 1 is converted to the Z-derivative or to the W—A⁶ derivative 2 (e.g. ZCl, Na₂CO₃, THF, H₂O or W—A⁶-introduction see scheme 3) (step a). Oxidation with TEMPO (2,2,6,6-Tetramethylpiperidine 1-oxyl, radical) and sodium hypochlorite gives ketone 3 (step b). Wittig reaction with (methoxymethyl)triphenylphosphonium chloride 4 in THF and potassium t-butoxide as base gives enolether 5 (step c), which is hydrolysed with 1 N HC ind THF at reflux (step d). The crude aldehyde 6 (as a cis/trans mixture) can be isomerised via bisulfite-adduct 7 (with disodium pyrosulfite in water/TBME, step e). Bisulfite adduct 7 can then be converted to the pure trans-aldehyde 8 with aqueous Na₂CO₃ in water/TBME (step f).

[0725] Scheme 2:

[0726] Scheme 2 shows the synthesis of aminothiols 4 that are used for the synthesis of compounds with thioether spacers. Triphenylmethanethiol is deprotonated with NaH in DMA and reacted with α,ω-dihaloalkane in DMA (step a). Treatment with the amine A¹A²NH yields the S-protected amine 3 (step b). Deprotection of the thiol moiety maybe achieved by treatment with TFA/triisopropylsilane in CH₂Cl₂ at 0° C. to RT to give the aminothiol 4 (step c).

[0727] Scheme 3:

[0728] The synthesis of ether derivatives of formula (I) is depicted in scheme 3. For the preparation of derivatives with n=0, the aminocyclohexanol derivative 1 can be treated under phase transfer conditions e.g. α,ω-dihaloalkanes, NaOH, nBu₄NHSO₄ to yield bromide 2. For n>0, alcohol derivative 1 may be treated with α,ω-dihaloalkane (for C₄ or longer alkanes) in the presence of NaH in DMF 0° C. to RT to yield bromide 2. For shorter alkanes the method of choice is the in situ generation of the haloalkane-triflate (from the corresponding haloalkanol with trifluoromethansulfonic anhydride/2,6-di-tert-butylpyridine in CH₂Cl₂ at 0° C.). This haloalkane-triflate is then reacted with alcohol 1 with 2,6-di-tert-butylpyridine as base in nitromethane at 60° C. to yield bromide 2 [following a procedure of Belostotskii, Anatoly M.; Hassner, Alfred. Synthetic methods. 41. Etherification of hydroxysteroids via triflates. Tetrahedron Lett. (1994), 35(28), 5075-6].

[0729] Amination of bromide 2 with amine A¹A²NH in DMA or DMF, at RT or in MeOH at RT to reflux yields the final amine 3, optionally DBU may be added. Amine 3 may be converted to a salt or to the N-oxide 4 using a mixture of hydrogen peroxide urea adduct and phthalic anhydride in CH₂Cl₂ at RT.

[0730] If A⁶W in 2 is a protecting moiety this can be cleaved using TFA in CH₂Cl₂ for BOC-groups or by hydrogenation in methanol/HCl with Pd/C for Z-groups. The resulting ammonium salt (not shown) may be treated according to one of the procedures described later to derive the appropriate A⁶W derivative which is then reacted with an excess of the amine A¹A²NH in DMA or DMF, at RT optionally with DBU or in MeOH at RT to reflux to yield the final amine 3.

[0731] Alternatively, the alcohol 1 can be converted to the amine 5 by attaching the pre-assembled fragment A¹A²NC(A³A⁴)(CH₂)_(m)—OH, which can be synthesized by known methods, to the mesylate/halogenide of derivative lusing alkylating conditions (step d). The amine 5 can be converted to its salt or the N-oxide 6 as described above (step c).

[0732] Finally, the substitution pattern for A⁶ in product 5 can be manipulated: e.g. hydrolysis of an acetyl group to an NH₂. Furthermore the substitution pattern of A¹ or A² may be modified, e.g. treatment of hydroxyethylamine with DAST.

[0733] If A⁶W in 3 or 5 is a protecting moiety this can be cleaved prior to salt or N-oxide formation using TFA in CH₂Cl₂ for BOC-groups or by hydrogenation in methanol with Pd/C for Z-groups. The resulting amine (not shown) may be treated according to one of the following procedures to derive the appropriate A6W derivative 3 or 5.

[0734] Sulfonamides: Sulfonylation of the amines is done in dioxane or CH₂Cl₂ with Hüenig's base and a sulfonyl chloride over night at RT to yield the sulfonamide 3 or 5.

[0735] Carbamates: The amines may be reacted with A⁶OCOCl/Hüenig's base in dioxane or CH₂Cl₂. Alternatively, the chloroformates may be prepared in situ by treatment of A⁶OH with Cl₃COCl in the presence of quinoline followed by reaction with the amines in the presence of Hüenig's base.

[0736] Thiocarbamates: The amines may be reacted with A⁶OCSCl in dioxane.

[0737] Ureas: The amines may be reacted with isocyanate in dioxane at room temperature.

[0738] Thioureas: The amines may be reacted with isothiocyanate in dioxane at room temperature.

[0739] Amides: The amines may be reacted with A⁵COCl/Hüenig's base in CH₂Cl₂, A⁶COOH/EDCI/DMAP (via formation of the symmetrical anhydride, and subsequent addition of the starting amine at −10° C. to room temperature) or alternatively with A⁶COOH/EDCI/DMAP or A⁶COOH/Hüenig's base or NMM/EDCI/HOBT in DMF, dioxane or CH₂Cl₂ at room temperature.

[0740] Sulfamides: The amines may be reacted with sulfamoyl chlorides in dioxane in the presence of an excess of triethylamine to yield sulfamide 3 or 5. The sulfamoyl chlorides can be prepared from A⁶NH₂ and chlorosulfonic acid in CH₂Cl₂ at 0° C. to room temperature followed by reaction with PCl₅ in toluene at 75° C. Alternatively, the sulfamoyl chlorides can be synthesized in acetonitrile with A⁶NH₂ and sulfuryl chloride at 0° C. to 65° C.

[0741] Scheme 4:

[0742] Scheme 4 shows the synthesis of thio ether derivatives of formula I in which V is S. For compounds in which n is 0, mesylation is performed under inversion (Mitsunobu conditions, step a). For compounds with n>0, the alcohol 1 can be mesylated with methanesulfonyl chloride in pyridine in the presence of DMAP at 0° C. to RT to yield sulfonate 2 (step a). Sulfonate 2 is then thiolated with the corresponding A¹A²aminoalkanethiol (in analogy to the methods described in context with scheme 2) with NaH as base in DMF at 0° C. to RT to give the final compound 3 or 5, respectively (step b).

[0743] Another approach for the synthesis of thioether 3, which opens up the possibility to vary the A¹A²amine terminus at the end, is depicted in steps d-f Sulfonate 2 is treated with potassium thioacetate in DMF at 100° C. to yield thioacetate 7. Deprotection with 1N LiOH in ethanol and alkylation with haloalkanol gives alcohol 8. The alcohol 8 is treated with methanesulfonyl chloride in pyridine in the presence of DMAP at 0° C. to RT to yield the mesylate/chloride which can be aminated with the corresponding A¹A²amine in the presence of NaI in DMA to yield the final amine 3. If WA⁶ is a protecting group this can be cleaved and the resulting amine can be converted to the desired WA⁶ derivative by employing one of the methods described for compounds 3 and 5 in scheme 3.

[0744] Finally, the substitution pattern for A⁶ can be manipulated: e.g. hydrolysis of an acetyl group to an NH₂. Furthermore the substitution pattern of A¹ or A² may be modified, e.g. treatment of hydroxyethylamine with DAST.

[0745] The amines 3 or 5 can optionally be converted to a salt or to the N-oxide 4 or 6 (step c, with e.g. hydrogen peroxide urea adduct and phthalic anhydride in CH₂Cl₂ at RT).

[0746] Scheme 5:

[0747] In scheme 5 the synthesis of C-analogues aminocyclohexanes of the general structure I in which V is —CH₂—, —CH═CH— or —C≡C— is described. The synthesis starts from aldehyde 1 which can be derived from (trans)-4-tert-butoxycarbonyl amino-cyclohexane-carboxylic acid (see scheme 1a, compound 9) or from the corresponding alcohol (compound 4, scheme 1a) by Swern oxidation. Side chain extension is effected through application of the Corey-Fuchs method. The aldehyde 1 is treated with triphenylphosphine, tetra-bromo-methane and triethylamine in CH₂Cl₂ at 0° C. to RT to yield 2,2-Dibromo-vinyl derivative 2. Rearrangement with n-BuLi (ca 1.6 M in hexane) in THF at −78° C., followed by reaction with formaldehyde (−78° C. to RT; step b) leads to the propargyl alcohol 3 [following conditions described in: Marshall, James A.; Bartley, Gary S.; Wallace, Eli M. Total Synthesis of the Pseudopterane (−)-Kallolide B, the Enantiomer of Natural (+)-Kallolide B. J. Org. Chem. (1996), 61(17), 5729-5735; and Baker, Raymond; Boyes, Alastair L.; Swain, Christopher J. Synthesis of talaromycins A, B, C, and E. J. Chem. Soc., Perkin Trans. 1 (1990), (5),1415-21.].

[0748] For longer side chains, the rearrangement of dibromoalkene 2 is performed with n-BuLi (ca 1.6 M in hexane) in THF at −78° C. as above, followed by addition of a cosolvens such as DMPU and reaction with O-protected 1-bromo-alcohols 4a (e.g. 1-bromo-n-tetrahydro-pyaranyloxyalkane) to yield the O-protected compounds 3 which can be deprotected to the corresponding alkinol 3 derivative in MeOH at 50-60° C. in the presence of catalytic amount of pyridinium toluene-4-sulfonate (step c). Alternatively, the side chain elongation of dibromoalkene 2 can also be performed with chloroalkaneiodide 4b (m>1) under the same conditions as described above to give directly chloride 5. Chloride 5 is then converted via iodide 5 (Finkelstein reaction) to the amine 6 as described later.

[0749] Mesylation of alcohol 3 with methanesulfonylchloride, pyridine and DMAP in CH₂Cl₂ at 0° C. to RT yields mesylate 5 which can be converted to the amine 6 in DMA or MeOH at RT or at 50-70° C. with an excess of the corresponding amine NHA¹A² (step e).

[0750] If A⁶W is a protecting moiety this can be cleaved prior to salt or n-oxide formation using TFA in CH₂Cl₂ for BOC-groups or by hydrogenation in methanol with Pd/C for Z-groups. The resulting amine (not shown) may be treated according to one of the procedures described for scheme 3 to yield the appropriate A⁶W derivative 6.

[0751] Optionally the introduction of the desired A⁶W moiety can be performed at an earlier stage, e.g. derivative 2 or O-protected derivative 3 or mesylate, chloride or iodide 5 to enable an optimization of the NA¹A² terminus at the final step e.

[0752] To obtain compounds 6 in which A³ and/or A⁴ is not H and m>0, compounds 2 can be reacted with compounds 10 under the same condition as described for step c. The building blocks 10 can be prepared by known methods. For the introduction of the group (A¹,A²)N—C(A³,A⁴)— wherein A³ and/or A⁴ is not H and m=0, a two step procedure has to be followed: first the rearrangement with n-BuLi (ca 1.6 M in hexane) in THF at −78° C., followed by reaction with the corresponding aldehyde (A³ or A⁴—COH) or ketone (A³COA⁴, at −78° C. to RT) leading to the A³,A⁴ substituted propargyl alcohol which can be transformed to a phosphorester or a chloride (not shown) and reacted with the desired (A¹,A²)-amine in the presence of Tetrakis(triphenylphosphine)palladium (for the phosphorsester) or Cu(I)Cl/Cu bronze and Hüenig's base for the chloride to yield the desired A³,A⁴-substituted compound 6 (step h). (see: Bartlett, Paul A.; McQuaid, Loretta A. Total synthesis of (□)-methyl shikimate and (□)-3-phosphoshikimic acid. J. Am. Chem. Soc. (1984), 106(25), 7854-60 and Cooper, Matthew A.; Lucas, Mathew A.; Taylor, Joanne M.; Ward, A. David; Williamson, Natalie M. A convenient method for the aromatic amino-Claisen rearrangement of N-(1,1-disubstituted-allyl)anilines. Synthesis (2001), (4), 621-625.)

[0753] Compounds in which V is —CH₂— or —CH═CH— can be obtained by hydrogenation of compound 6 with Pt/C (yields the saturated analogue 8) or by hydrogenation with other known methods (yields the double bond analogue 8). Alternatively, the alkyne group can already be reduced at an earlier stage e.g. alcohol 3 (e.g. LAH-reduction for m=0, gives V=trans —CH═CH— or hydrogenation with Pt/C or PtO₂.H₂O yields V=CH₂CH₂—), and the resulting compound can be transformed further to the final compounds 8 and/or 9.

[0754] Finally, the substitution pattern for A⁶ can be manipulated on amine 6 or 8: e.g. hydrolysis of an acetyl group to an NH₂. Furthermore the substitution pattern of A¹ or A² may be modified, e.g. treatment of hydroxyethylamine with DAST.

[0755] The amines 6 and 8 can be converted to a salt or as described in step f to the N-oxide 7 and 9, respectively, using a mixture of hydrogen peroxide urea adduct and phthalic anhydride in CH₂Cl₂ at RT.

[0756] Scheme 6:

[0757] The synthesis of C-analogues in which V is —CH₂— or —CH═CH— is depicted in scheme 6. Alcohol 1 (see synthesis of alcohol 4 in Scheme 1a) can be transformed to the aldehyde 2 via Swern-oxidation. Alternatively, alcohol 1 can be tosylated (tosylchloride in pyridine) followed by treatment with NaCN (in DMF at 100° C.) and reduction with DIBALH (−78° C. to RT in THF) to give the Cl-elongated aldyhyde 2. Horner-Emmons reaction with triethyl phosphono acetate, sodium methanolate in ethanol yields the unsaturated ester 3 (step b). Ester 3 can either be reduced directly to the unsaturated alcohol 4 (V is —CH═CH—, x=1) or can be hydrogenated with 10% Pd/C in methanol and reduced with lithium aluminum hydride in THF to the saturated alcohol 4 (V is —CH₂—, x=2). The alcohol is mesylated with methane sulfonyl chloride, triethylamine in CH₂Cl₂ to yield mesylate 5 (step d) which is treated with the desired amine A A²NH to yield the derivative 6 (step e). As described for the previous schemes, for the cases A⁶W is a protecting group (BOC or Z), this can be cleaved and the appropriate A⁶W moiety introduced using the methods shown in scheme 3.

[0758] Finally, the substitution pattern for A⁶ can be manipulated on amine 6: e.g. hydrolysis of an acetyl group to an NH₂. Furthermore the substitution pattern of A¹ or A² may be modified, e.g. treatment of hydroxyethylamine with DAST.

[0759] The amines 6 can be converted to a salt or, as described in step f, to the N-oxide 7 using a mixture of hydrogen peroxide urea adduct and phthalic anhydride in CH₂Cl₂ at RT.

[0760] Alternatively the side chain can be directly introduced by treatment of aldehyde 2 via Wittig-reaction to give bromide 5 (step g; aldehyde 2 and Wittigsalt 8 was refluxed in the presence of K₂CO₃ or Cs₂CO₃ in 2-methyl-2-butanol). Bromide 5 can be transformed directly to amine 6 or N-oxide 7 as described above. For the cases A⁶W is a protecting group (BOC or Z), this can be cleaved (i.e. first selective hydrogenation of the double bond with Pt/C, H₂ in toluene followed by cleavage of the Z-protection with HBr (33%) in acetic acid) on the stage of 5 or 6 and the appropriate A⁶W moiety can be introduced using the methods shown in scheme 3.

[0761] Scheme 7:

[0762] Another approach for the introduction of the substituted side chain is depicted in scheme 7. It starts by attaching an ω-hydroxycarbonic acid ester via the in situ generated triflate in analogy to Belostotskii, Anatoly M.; Hassner, Alfred. Synthetic methods. 41. Etherification of hydroxysteroids via triflates. Tetrahedron Lett. (1994), 35(28), 5075-6(step a). Alternatively, the ester 2 can be prepared from the bromide 3 (synthesis according to scheme 3) by treatment with e.g. acetocyanhydrine in acetonitrile, followed by a Pinner reaction and hydrolysis of the imidate to the corresponding ester (step b).

[0763] For V═CH═CH, the ester 2 or its corresponding acid may be prepared from aldehyde 4 (synthesis described in scheme 6) by treatment with the corresponding Wittig reagent Ph₃P(CH₂)^(m+1)CO₂R/H. For V═C, hydrogenation of the Wittig product under standard conditions yields the saturated product 2.

[0764] For V═CC, ester 2 or amide 6 may be derived from the dibromoderivative 5 (synthesis according to scheme 5) by rearrangement with n-BuLi (ca 1.6 M in hexane) in THF at −78° C., followed by reaction with chloroformate or dimethylcarbamoyl chloride (−78° C. to RT; step d). For longer side chains, the rearrangement of dibromoalkene 5 may be performed with n-BuLi (ca 1.6 M in hexane) in THF at −78° C. as above, followed by addition of a cosolvens such as DMPU and reaction with a suitable protected 1-bromo-alkylalcohol Br—(CH₂)_(m)CH₂OH, followed by oxidation to yield the compound 2 as acid (step e).

[0765] Saponification of the ester 2 using standard conditions e.g. LiOH in EtOH, MeOH or THF, followed by treatment with NHA¹A², EDCI, HOBT and a base such as Hüenig's base, NEt₃, NMM in CH₂Cl₂, DMF, DMA or dioxane gives amide 6. Amide 6 can be transferred to amine 7 (A³,A⁴═Me) by reaction with methylmagnesium bromide, ZrCl₄ in THF at low temperature (see Stephen M. Denton, Anthony Wood, A Modified Bouveault Reaction for the Preparation of α,α-dimethylamines from Amides, Synlett 1999,1, 55-56.) or by treatment with other grignard reagents in the presence of ZrCl₄ or Ti(OiPr)₄ (see V. Chalinski, A. de Meijere, A versatile New Preparation of Cyclopropylamines from acid dialkylamides, Angew.Chem. Int. Ed. Engl. 1996, 35, No4, 413-4.).

[0766] For A¹═Me, A^(2′)═OMe, the amide 3 can be treated with a grignard reagent A³Mgx to give the corresponding ketone 8. Reductive alkylation of the ketone 8 by treatment with NHA¹A² in the presence of tetraisopropyl orthotitanate, followed by reduction with NaCNBH₃ in ethanol yields the amine 7 (see: R. J. Mattson, K. M. Pham, D. J. Leuck, K. A. Cowen, J. O. C. 1990,55,2552-4.).

[0767] Amine 7 maybe converted to a salt or to the N-oxide 9 using a mixture of hydrogen peroxide urea adduct and phthalic anhydride in CH₂Cl₂ at RT.

[0768] If A⁶W is a protecting moiety this can be cleaved prior to salt or N-oxide formation using TFA in CH₂Cl₂ for BOC-groups or by hydrogenation in methanol with Pd/C for Z-groups. The resulting amine (not shown) may be treated according to one of the procedures described before (scheme 3) to derive the appropriate A⁶W derivative.

[0769] Pure cis- or trans-aminocyclohexane derivativescan be obtained either by separation of the mixtures using HPLC or by using stereochemically defined starting materials.

[0770] The following tests were carried out in order to determine the activity of the compounds of formula I and their salts.

[0771] Inhibition of Human Liver Microsomal 2,3-oxidosqualene-lanosterol Cyclase (OSC)

[0772] Liver microsomes from a healthy volunteer were prepared in sodium phosphate buffer (pH 7.4). The OSC activity was measured in the same buffer, which also contained 1 mM EDTA and 1 mM dithiothreitol. The microsomes were diluted to 0.8 mg/ml protein in cold phosphate buffer. Dry [14C]R,S-monooxidosqualene (MOS, 12.8 mCi/mmol) was diluted to 20 nCi/l with ethanol and mixed with phosphate buffer-1% BSA (bovine serum albumin). A stock solution of 1 mM test substance in DMSO was diluted to the desired concentration with phosphate buffer-1% BSA. 40 μl of microsomes were mixed with 20 μl of the solution of the test substance and the reaction was subsequently started with 20 μl of the [¹⁴C]R,S-MOS solution. The final conditions were: 0.4 mg/ml of microsomal proteins and 30 μl of [¹⁴C]R,S-MOS in phosphate buffer, pH 7.4, containing 0.5% albumin, DMSO <0.1% and ethanol <2%, in a total volume of 80 μl.

[0773] After 1 hour at 37° C. the reaction was stopped by the addition of 0.6 ml of 10% KOH-methanol, 0.7 ml of water and 0.1 ml of hexane:ether (1:1, v/v) which contained 25 μg of non-radioactive MOS and 25 μg of lanosterol as carriers. After shaking, 1 ml of hexane:ether (1:1, v/v) was added to each test tube, these were again shaken and then centrifuged. The upper phase was transferred into a glass test tube, the lower phase was again extracted with hexane:ether and combined with the first extract. The entire extract was evaporated to dryness with nitrogen, the residue was suspended in 50 μl of hexane:ether and applied to a silica gel plate. Chromatographic separation was effected in hexane:ether (1:1, v/v) as the eluent. The Rf values for the MOS substrate and the lanosterol product were 0.91 and, respectively, 0.54. After drying, radioactive MOS and lanosterol were observed on the silica gel plate. The ratio of MOS to lanosterol was determined from the radioactive bands in order to determine the yield of the reaction and OSC inhibition.

[0774] The test was carried out on the one hand with a constant test substance concentration of 100 nM and the percentage OSC inhibition against controls was calculated. The more preferred compounds of the present invention exhibit inhibitions larger than 50%. In addition, the test was carried out with different test substance concentrations and subsequently the IC₅₀ value was calculated, i.e. the concentration required to reduce the conversion of MOS into lanosterol to 50% of the control value. The preferred compounds of the present invention exhibit IC₅₀ values of 1 nM to 10 μM, preferrably of 1-100 nM.

[0775] The compounds of formula I and their pharmaceutically acceptable acid addition salts can be used as medicaments, e.g. in the form of pharmaceutical preparations for enteral, parenteral or topical administration. They can be administered, for example, perorally, e.g. in the form of tablets, coated tablets, dragees, hard and soft gelatine capsules, solutions, emulsions or suspensions, rectally, e.g. in the form of suppositories, parenterally, e.g. in the form of injection solutions or infusion solutions, or topically, e.g. in the form of ointments, creams or oils.

[0776] The production of the pharmaceutical preparations can be effected in a manner which will be familiar to any person skilled in the art by bringing the described compounds of formula I and their pharmaceutically acceptable acid addition salts, optionally in combination with other therapeutically valuable substances, into a galenical administration form together with suitable, non-toxic, inert, therapeutically compatible solid or liquid carrier materials and, if desired, usual pharmaceutical adjuvants.

[0777] Suitable carrier materials are not only inorganic carrier materials, but also organic carrier materials. Thus, for example, lactose, corn starch or derivatives thereof, talc, stearic acid or its salts can be used as carrier materials for tablets, coated tablets, dragees and hard gelatine capsules. Suitable carrier materials for soft gelatine capsules are, for example, vegetable oils, waxes, fats and semi-solid and liquid polyols (depending on the nature of the active ingredient no carriers are, however, required in the case of soft gelatine capsules). Suitable carrier materials for the production of solutions and syrups are, for example, water, polyols, sucrose, invert sugar and the like. Suitable carrier materials for injection solutions are, for example, water, alcohols, polyols, glycerol and vegetable oils. Suitable carrier materials for suppositories are, for example, natural or hardened oils, waxes, fats and semi-liquid or liquid polyols. Suitable carrier materials for topical preparations are glycerides, semi-synthetic and synthetic glycerides, hydrogenated oils, liquid waxes, liquid paraffins, liquid fatty alcohols, sterols, polyethylene glycols and cellulose derivatives.

[0778] Usual stabilizers, preservatives, wetting and emulsifying agents, consistency-improving agents, flavour-improving agents, salts for varying the osmotic pressure, buffer substances, solubilizers, colorants and masking agents and antioxidants come into consideration as pharmaceutical adjuvants.

[0779] The dosage of the compounds of formula I can vary within wide limits depending on the disease to be controlled, the age and the individual condition of the patient and the mode of administration, and will, of course, be fitted to the individual requirements in each particular case. For adult patients a daily dosage of about 1 mg to about 1000 mg, especially about 50 mg to about 500 mg, comes into consideration for the prevention and control of topical and systemic infections by pathogenic fungi. For cholesterol lowering and treatment of impaired glucose tolerance and diabetes the daily dosage conveniently amounts to between 1 and 1000 mg, preferably 10 to 100 mg, for adult patients. Depending on the dosage it is convenient to administer the daily dosage in several dosage units.

[0780] The pharmaceutical preparations conveniently contain about 1-500 mg, preferably 10-100 mg, of a compound of formula I.

[0781] The following Examples serve to illustrate the present invention in more detail. They are, however, not intended to limit its scope in any manner.
